[arch-general] How to cache pacman mirror for LAN
by Takayuki Muranushi 05 Jun '11

05 Jun '11

Hello, I'm building a computer cluster with about 20 nodes, all of them running ArchLinux. One of them is the 'login' node connected to the Internet, other nodes share Internet connection via the login node being a router. https://wiki.archlinux.org/index.php/Internet_Share Now, when I update the system (pacman -Syu) or install package on all node, I think it's a bad idea because it will consume the mirror bandwidth proportional to the number of the nodes. Maybe it's not a big issue for 20 nodes, but I'd like to learn nevertheless for future use, that: Is there a way to cache the pacman transaction at the login node, so that the communication between the login node and the mirror is constant, and the rest of communications only take place within the LAN? Is seting up a pacman mirror at the login node is the correct solution? Best, Takayuki Muranushi

[arch-general] Lyx 1.6 vs. 2.0
by Bernardo Barros 05 Jun '11

Hi, Is there a reason not to update Lyx 1.6 to 2.0? Or at least create two packages lyx1 and lyx? Is there known bugs there? Best! Bernardo

My /usr is on a separate partition and my loopback is not starting, but everything appears to work well. From the timing I would assume one is the mkinitcpio and one is rc.sysinit but thought I would check first.

[arch-general] initscripts change
by Carl Mueller 03 Jun '11

03 Jun '11

Why change the modules array in initscripts? I always read that Arch was great because almost all configurations were done in one file, namely rc.conf.

[arch-general] "whitebox" on bootup after KMS kicks in
by C Anthony Risinger 02 Jun '11

02 Jun '11

does anyone else experience <title>? i've been getting this for sometime -- on intel, nouveau, and radeon KMS drivers -- and it looks terrible. after the module loads within initramfs, the space *within* the old resolution is pure white, surrounded by normal black. i'm pretty sure the "whitebox" corresponds to the size of the previous resolution because it's different sizes on all my machines, and pretty small on my 1920x1280 laptop (@ 15.5in ... awesome :-) anyways, long story short it turns back 2 black when written over (systemd/initscripts output) or cleared, so: echo -en '\e[H\e[2J' ... takes care of it. i basically just did a `clear > out`, looked at the codes, and made a small initramfs hook from the above. it works fine as is, but is anyone else seeing this? it annoys me because i don't run getty on tty1, so it's there forever unless i clear right away. not really a big deal, as it took longer to write this msg than fix it, but it started happening a few kernels ago IIRC and i'm wondering if we can just throw something like this into mkinitcpio (if `quiet`, or before output), because it looks terrible :-( i'll open a report unless someone feels like throwing it in there, it's a pretty simple change. -- C Anthony

[arch-general] Salt update to 0.8.8
by Thomas S Hatch 01 Jun '11

01 Jun '11

I have not mentioned this here for a while, but I am a big fan of seeing what the Arch community is developing, and in the past I have gotten some real interest from the Arch community on this front. I just released Salt 0.8.8, salt is an application used for very fast remote management of systems via zeromq. Salt allows you to manage large groups of servers from a master server with simple commands, and salt also contains functionality for configuration management. Salt is meant to fill the roles of applications like puppet, mcollective, func, cgengine, fabric, Capistrano and many others. The release announcement is here: http://red45.wordpress.com/2011/05/30/salt-0-8-8/ Arch package is here: https://aur.archlinux.org/packages.php?ID=47512 Video explaining how to use Salt and what it is in detail is here: http://blip.tv/thomas-s-hatch/salt-0-8-7-presentation-5180182 And the (under heavy development) website and docs are here: http://thatch45.github.com/salt-www/ Salt is developed on Arch, but is made to run on any Linux/BSD Let me know what you all think! -Thomas S Hatch
